Paper content viewports with a circle / spline / ellipse clip boundary
drew their model content to the full bounding rectangle instead of the
shape. Each paper content viewport is its own render into its own screen
rectangle, so clipping is done per viewport: the boundary polygon is
projected into that viewport's render-target NDC (paper shape mapped
through the same visible-sub-rect crop as the content, so it stays fixed
to the viewport frame) and stamped into the stencil buffer with an
even-odd Invert, which marks the interior of any shape, convex or not,
without triangulation. Every content pass then draws only where the
stencil is set, so hatch, wire, mesh, 3DFACE, text, image, wipeout and
selection are all clipped uniformly.
Because Invert turns the cleared 0x00 into 0xFF, clipped content draws
with stencil reference 0xFF (unclipped content keeps reference 0). The
shared depth buffer moves to Depth24PlusStencil8 across every pipeline.
Rectangular viewports keep clipping via their own render rectangle and
XCLIP keeps its existing CPU wire clip; neither needs the stencil path.

glam 0.33.2 deprecated Mat4::{orthographic,perspective,look_at}_rh in
favour of the glam::camera::rh::* functions. Switch the 7 call sites in
camera.rs and viewcube.rs to the equivalent camera-module functions
(directx orthographic/perspective = same [0,1] depth range; look_at_mat4
= same view matrix), silencing the deprecation warnings. No behaviour
change.

Reduce the ViewCube 30% (VIEWCUBE_PX 120→84) and tighten the nav region
(NAV_INSET_F 2.2→2.0) so the home / roll / nudge controls hug the cube in the
corner instead of floating in a large dead area, with sizes scaled to keep them
from overlapping. Bump the home and roll buttons back up slightly, shift the
UCS picker down below the region, and give it a fixed width so it centres
exactly under the cube centre.

The UCS icon now anchors to the projected UCS origin when it is on-screen
(falling back to the bottom-left corner), and becomes a selectable object:
hover highlights it, a click shows draggable grips, and dragging the origin
grip relocates the UCS while the X/Y tip grips rotate it. Drags snap to
geometry/grid through the existing snapper, and the new UCS is persisted on
release. The icon stays selectable while parked in the corner.
Also make the ViewCube compass (N/E/S/W) world-fixed: the cube body still
reorients with the active UCS, but the cardinals project through a camera-only
rotation and snap in world frame, so the directions no longer spin with the UCS.

Build the ViewCube out into a full navigation widget:
- Compass ring painted in the cube's ground plane (z = base) so it
reads as a ground compass and foreshortens with the view.
- N/E/S/W cardinals painted flat onto the ring band; clicking one snaps
to that side elevation. Added S/W glyphs to the bitmap atlas.
- Home button (top-down view), roll arrows (90° roll about the view
axis), and four nudge triangles (90° tip/spin) as SVG iced controls
laid out around the cube. New home.svg.
- WCS / named-UCS selector under the cube, switching the active UCS.
The cube hit area now shares one stack with the control buttons, so a
click on a button is caught by the button while a click on the cube
falls through. Face clicks snap to the highlighted region rather than a
cursor position the viewport's move handler can overwrite.
Camera gains home_view / roll_by / nudge_90; floating viewports drive
the same ops through mutate_active_viewport_camera, which re-encodes the
result to the stored view direction + twist.

Lay each label's glyph quads out in the face's own local plane and
project the corners individually, instead of drawing screen-aligned
billboard text at the projected face centre. The letters now skew with
perspective and sit on the surface as the cube rotates.
Per-face (u, v) basis vectors are chosen so u x v equals the outward
normal, which keeps the text from ever reading mirrored.

Koordinat girişi artık göreli/mutlak ayrımını destekliyor:
- `@x,y[,z]` → son girilen noktaya göreli (UCS eksenlerinde döndürülür)
- `#x,y[,z]` → her zaman mutlak (DYN durumundan bağımsız)
- ön ek yok → DYN açıksa göreli, kapalıysa mutlak
İlk noktada referans olmadığından göreli giriş mutlağa düşer. Çözülen
WCS noktası last_point olarak saklanıyor, böylece ardışık göreli
girişler zincirleniyor.
parse_coord artık (Vec3, CoordKind) döndürüyor; relative offset için
ucs_rotate_vec eklendi (origin translation olmadan UCS rotasyonu).
UCS ORIGIN komutu prefix'i yok sayıp mutlak kalıyor.
Ayrıca ViewCube snap refactor'undan kalan kullanılmayan kod temizlendi:
angle_close, active_viewport_yaw_pitch, CubeRegion::snap_angles.

ViewCube tıklaması artık sabit (yaw, pitch) tablosu yerine bir yön
vektörüne (eye direction) snap ediyor. Up vektörü şöyle seçiliyor:
1. Mevcut up alın.
2. ±X / ±Y / ±Z arasından (yeni gaze ile (anti-)paralel olmayanlar)
mevcut up'a en yüksek dot-product veren cardinal axis'i seç.
3. Bu axis'i yeni gaze yönüne dik plane'e projekte et ve up olarak
kullan.
Sonuç:
- Küçük tilt'ler ilgili canonical axis'e snap olarak temizleniyor.
- TOP yukarıda iken TOP-LEFT edge tıklayınca TOP yukarıda kalıyor;
cube edge'e dönüyor ama kullanıcının "yukarı" hissi korunuyor.
- Upside-down orbit edilmişse -Z up olarak seçilir, snap baş aşağı
yapılandırmayı bozmuyor.
CubeRegion::snap_angles ve Camera::snap_to_angles yerini
snap_direction / snap_to_direction aldı.
snap_active_viewport_to_direction viewport'un view_direction'ını
günceller, twist_angle'a dokunmaz.

Two behaviour changes that bring the command line in line with
established CAD workflow:
1. **Always-on keyboard capture.** The input was blurred whenever no
command was running, so typed letters went nowhere until the user
clicked into the field. Replace the blur with a re-focus on every
command lifecycle transition (cmd_result.rs) and on viewport / tab
/ ribbon clicks (update.rs), focus the input at startup, and add
a global key subscription that catches any unhandled character key
or backspace and routes it into the buffer via two new messages
(CommandAppendChar / CommandBackspace) — so the command line keeps
accumulating keystrokes even if focus parks somewhere not
focusable. Removes the unused blur_cmd_input helper.
2. **Space submits.** Typing a space at the end of the input now
submits the buffer the same way Enter does. Only exception: an
active command that's currently collecting free-form prose
(TEXT / MTEXT / DDEDIT body, ATTDEF prompt / default value,
INSERT attribute value, ATTEDIT cell). Those advertise the new
`CadCommand::wants_text_with_spaces()` flag so the Space character
reaches the buffer as a literal.

- Hide OS crosshair and drawn crosshair when cursor is over ViewCube area
- Enhanced hover glow in WGSL shader (blue tint + brightness boost)
- Fixed region_centroids() Y-axis sign for all FRONT/BACK-related regions
- Swapped corner geometry assignments (TPF↔TBK, BTF↔BBK) to match
intended FRONT/BACK semantics (sy=-1 = FRONT, sy=+1 = BACK)
- Corrected all snap_angles: yaw_pitch_to_quat(0,0) places eye at -Y
(FRONT view), so FRONT=0 and BACK=PI — cascaded through edges/corners
